3 USE CASE QoS management and reporting for NOC CUSTOMER SITUATION A large European mobile operator required to share network performance data with internal stakeholders at different levels: high-level for top management to detailed data for NOC engineers, offering quick drilldown to identify QoS problems. It was important to process and present Performance Management data in an easy and comprehensive form for quick analysis, either pre-configured or customizable within specified limits. A web interface with pre-aggregated reports was recommended as an important way to display and access PM data. Also, exporting the data into different common formats would help the user to distribute the relevant data for operations and optimization teams to take parallel actions. Besides presenting data to the various stakeholders, the operator required that a comparison be made between regional network quality and network-wide performance. By analyzing a predefined report for each region, a quick and comprehensive view on overall performance would be established. SOLUTION With MYCOM OSI s PrOptima NOC dashboard, reports were generated that offered a quick view of the overall network performance, in addition to regional performance data. BENEFITS Web-based access for organizationwide reporting Top KPI visualization for NOC engineers Easy-to-understand charts/graphs/ tables GIS view of locations mapped with performance data Suggested drilldowns for quick RCA QUICK FACTS Customer: European mobile operator with 42 million subscribers MYCOM OSI solutions: PrOptima Domains: RAN, circuit-switched core, packet-switched core, evolved packet core, IMS Core, IN, VAS Technologies: GSM, UMTS, LTE Vendor equipment: NSN, Ericsson, Huawei, Alcatel-Lucent NOC dashboard for 4G service and OTT health Some of the reports created were color-coded coverage plots for all 2G, 3G and 4G for specific locations or for the entire network. Reports were also generated for throughput of a particular network area (cell cluster, cell). The dashboards were pre-aggregated as per customer s requirement.

4 PrOptima Web Reporter screen Some of the KPIs correlated with a GIS map were: GIS view of network elements identifying 2G/3G/4G KPIs Handovers between 2G, 3G and 4G Availability of sites Integrity - Traffic data volume, latency, jitter, packet loss, throughput, etc. GIS views could be quickly arranged in PrOptima through drag-and-drop operation and correlation capability to render the results of an investigation, e.g. identifying the coverage area affected by a KPI degradation in a cell cluster. Conversely, a selection in a GIS view was used as filter criteria to trigger table/graph views. RESULTS Predefining reports in the dashboard helped to offer a high-level view for C-level and NOC manager. The easy-tounderstand graphs and charts help identify the most critical performance issues across the network. KPIs that had the most impact on quality of experience were highlighted and tracked in near real time. Suggested views for drill-down action The detailed NOC reports were customized as per engineer/management needs through simple drag-and-drop functions. The reports were analyzed by the operator s quality engineer, network domain manager and NOC manager. After identifying problems on the dashboard, the NOC engineer could drill down into the root cause of the degrading KPI, e.g. Health Index. PrOptima suggested views took the engineer to the next level of troubleshooting, identifying the candidate cells to optimize.

5 USE CASE Resolving E2E network capacity bottlenecks CUSTOMER SITUATION A large European mobile network was buckling under the growing demand for new mobile data services. Frequent network enhancements were made to avoid data congestion and bottlenecks, requiring the operator to closely monitor the network capacity to enhance capacity of various network elements. In the absence of a proactive performance monitoring system, the user had to constantly monitor the network activities to prevent congestion, often reacting late. In addition to this, predefined reports on specific capacity KPIs were not available. These were important for proactive capacity upgrades. Also, there was no flexibility to create capacity reports on an E2E network-wide basis. Threshold-based capacity alarms, performance trends and Worst-N/Best-N reports were critically required to resolve the capacity problems. SOLUTION With the MYCOM OSI PrOptima, the mobile operator was able to carry out periodic and proactive observation of network utilization on a daily, weekly, and/or monthly basis. This was achieved through performance alarms, performance monitoring and Worst-N reports. BENEFITS Support network planning by identifying locations with immediate capacity needs Strategic proactive capacity planning Increase speed of capacity upgrades and prevent bottlenecks Reduce Opex through predefined capacity KPI reporting QUICK FACTS Customer: European mobile operator with 42 million subscribers MYCOM OSI solutions: PrOptima Domains: RAN, circuit-switched core, packet-switched core, evolved packet core, IMS core, IN, VAS Technologies: GSM, UMTS, LTE Vendor equipment: NSN, Ericsson, Huawei, Alcatel-Lucent Processor loads, PRB and DRB utilization (UL and DL) PrOptima uses flexible reporting, not requiring SQL or external BI integration, offering off-the-shelf, weekly BH reports based on daily BH values, ranked across different days of the same week. The steps taken by the NOC engineer included viewing the Worst-N reports and verifying the problem by analyzing impact on the network, at the dashboard level. By checking the KPIs against the baseline and its trend, the operator was guided to drill down into the problem locations where the capacity bottlenecks were observed.

6 Network congestion time By analysing the impact of capacity bottlenecks and assigning priorities, PrOptima helped the Planning/Optimization engineer to focus and identify actions to be taken to address the capacity problem. After this, the user could confirm fixes to the problems. The system was extensively used by the network planners, system engineers and quality engineers. RESULTS With PrOptima, the optimization engineer was able to carry out periodic and proactive observation of network capacity, and readily receive performance alarms over the dashboard, and SMS. The user could navigate between Worst-N, trend reports, capacity alarms to high-level dashboards. The user could also suspend capacity alarms for a certain time and network element. Other PrOptima features that were used were alarm generation, scheduled reports, report and ing by event. A capacity analysis report on LTE cells allowed detection of cell identities that showed a consistent high level of traffic over a period of several weeks; a set of KPIs defined as counter aggregations over BH points in time; topology filters based on thresholds set on such KPIs and, finally, reports listing the cell identities that show multiple threshold breaches over a period of several weeks.

7 USE CASE Eliminating performance problems through worst cell cluster analysis CUSTOMER SITUATION A large European multi-vendor mobile operator wanted to identify worst performing cells and cell clusters in its 2G, 3G and 4G networks to quickly eliminate rogue or underperforming cells/clusters. A daily worst cell list with related reports/dashboards (daily, hourly) was required to be viewed every few seconds. The ranking of the worst cells/clusters was to be based on the Health Index KPI (comprising RRC/RAB establishment failure rate, UL and DL volumes, etc.). The Health Index KPI was to be augmented by external data, e.g. ARPU for cell/node B in order to prioritize actions. There was a need for regional and national worst cell lists to be generated and ed to users daily. The report was to be based on averages and standard deviation for the KPI for the last 30 days. The worst cell report also had to offer drilldown from national to regional level, KPIs to counter level in order to isolate the issues. A cluster analysis was also required based on high-level KPIs to analyze the worst clusters of a region. The Cluster KPIs would show the aggregated values pointing to certain problems in the network. The user would then drill down to the single elements. Additionally, PM reports were expected to offer correlation between different report types, e.g. GIS to graphs/tables and vice versa. SOLUTION Worst cell list was created in the MYCOM OSI PrOptima adding different KPIs to a report and defining thresholds for the results. To create a worst cell list, a number of multi-vendor and multi-technology KPIs were taken into account. The PrOptima reports have flexible dimensions, e.g. thresholds, time, network element, technology type, vendor type etc., allowing flexibility to the user to create the criteria for worst cells. BENEFITS Quick identification of worst offenders (within seconds) on network level as well as regional level GIS view to visualize and correlate badly performing cells/cluster to its Health Index Quick navigation between GIS view and other reports (Tables/Graphs) Reduce MTTR QUICK FACTS Customer: European mobile operator with 42 million subscribers MYCOM OSI solutions: PrOptima Domains: RAN, circuit-switched core, packet-switched core, evolved packet core, IMS Core, IN, VAS Technologies: GSM, UMTS, LTE Vendor equipment: NSN, Ericsson, Huawei, Alcatel-Lucent LTE accessibility-based worst cells/cluster on GIS map

8 The GIS module was offered to visualize the cluster with a color-code to indicate its health. Drilling down into a cluster showed the single elements, the KPIs and counters within the GIS module. In absence of predefined clusters, polygons were used to group network elements. 2G/3G/4G worst cells/clusters based on Health Index The optimization engineer was able to check the worst cell report or performance alarm report using predefined dashboards of PrOptima. After comparing the KPI and the baseline, they could analyze the impact of violations and assign priorities for activities to fix the problem. For the worst cluster reporting, the optimization engineers used worst cluster report for analysing root causes. After checking daily KPIs against the baseline, they could analyze different scenarios such as configuration changes, new integration, cell performance and worst cells of a cluster. PrOptima was extensively used by the operator s RAN Experts and system engineers. GIS views were quickly arranged using drag-and-drop operations to define different data reports, e.g. identifying the coverage area affected by a KPI degradation in a cell cluster. Conversely, a selection in a GIS view was used as a filter criteria to drill down to tabular/graphical reports. RESULTS Using PrOptima, the engineers could generate the worst cell lists generated within a few seconds. PrOptima allowed analyzing the impact of violations and assigning priorities using both drill-down and roll-up functions, as required by the operator. After visualizing clusters in GIS and performing a drilldown/roll up using polygons, grouping, and area filters, the engineers could isolate the worst cells/clusters within seconds, enabling optimization activities on those cells/clusters.

9 USE CASE Simplifying RAN optimization for successful LTE deployments Customer Situation To accommodate a rapid growth in mobile broadband data usage and subscribers, a major mobile operator was accelerating its Long Term Evolution (LTE) coverage with new deployments as well as optical carrier adds. The new networks needed to be turned on quickly and with optimum performance while making efficient use of network and human resources. From a customer service perspective it was critical to maintain service quality before, during, and after the launches took place. This was challenging because of LTE s complexity, the rapid pace of deployments, and limited staff. The operator chose the MYCOM OSI NIMS-PrOptima performance management solution to ensure quality throughout the LTE network launches. Once live, NIMS-PrOptima continuously monitored the Radio Access Network (RAN) performance, capacity, and quality. Important criteria in the operator s decision to choose NIMS-PrOptima were its converged multi-vendor, multi-system (radio, circuit, and packet core networks), and cross-domain capabilities that integrated fault, performance, and configuration management data. Essential to rapid and accurate deployments were its flexible, out-of-the-box Key Performance Indicators (KPIs) and reports and powerful analysis and correlation features. Solution NIMS-PrOptima provided critical insights and analyses to network engineering and optimization departments, capacity planning and infrastructure rollout teams, and network service operations centres. Because of its flexibility and embedded LTE capabilities, it became an essential tool to optimize the LTE network before and after launch. Then, on an ongoing basis the networks were monitored continuously and optimized as needed for performance stability and capacity utilization. NIMS-PrOptima was used for coverage, resource allocation, and quality assurance engineering activities such as: Pre- and post-launch optimization Macro and cluster optimization Carrier tuning Hotspot and worst cell detection Localization of degraded cells Handover and neighbor list optimization Parameter optimization and audits Capacity, traffic balancing, and expansion analysis BENEFITS Integrated performance, fault, and configuration management Improved efficiency through manual and automated workflows Flexible, out-of-the-box KPIs and reports aligned to workflow processes Advanced, automated correlation, analysis, reporting, and visualization capabilities Powerful, integrated GIS capabilities QUICK FACTS Customer: European mobile operator, mobile subscriber base >3 million MYCOM OSI solutions: NIMS-PrOptima Domains: RAN, circuit-switched core, packet-switched core, epc, VAS, IMS Technologies: GSM, UMTS, LTE Vendor equipment: NSN, Ericsson, Cisco, Huawei

10 The operator depended upon guided diagnostics automated and embedded business processes within decision trees that are triggered for manual or automatic network modifications. The underlying powerful decision support system automatically performed calculations on terabytes of performance data to identify underperforming or degraded network elements and then suggest actions for resolution. Automated root cause analysis helped to initiate immediate corrective action and ensured optimum performance through pre- and post-launch activities, network audits, and on-going network optimization. This focus on intelligent automation enabled staff to dramatically increase productivity and ensured consistency and quality in the resulting actions. For LTE pre-launch tuning, the operator initiated automatic LTE parameter audits that included recurring comparisons to standard parameter values and resulted in the automatic generation of command files. The NIMS-PrOptima underlying decision support system automatically performed calculations to create accurate script files and logs. Physical cell Identifier (PCI) collision conflicts were detected including potentially confusing situations. Because NIMS-PrOptima integrates fault management it detected active fault alarms at the ecell and enodeb levels and then suggested actions for resolution or, as desired, automatically made the changes required. An important part of post-launch optimization included LTE health index alerting and troubleshooting. The user could quickly open an out-of-the-box report on the health of an ecell. The health index is a composite index metric constructed from key LTE performance indicators such as accessibility, retainability, availability, and throughput. Root cause analysis can be performed with ease since NIMS-PrOptima correlates fault and configuration data with performance data. It analyzes, diagnoses, and correlates health index KPI values with historical configuration changes and active fault alarms. Health index alerting report results can be mapped using the GIS feature for easy analysis or with graphs and tables for deep diagnosis and drill-down at the click of a mouse. NIMS-PrOptima automatically troubleshoots the LTE handover process including decision, preparation, and execution while navigating from the ecell to neighbors and target cells and then suggesting resolution actions. Intra-LTE handover troubleshooting can be performed up to the Mobility Management Entity (MME) and across domains (RAN, Core). When site outages occur, the system can perform auto-recovery and self-healing to resolve the problem. To identify degraded cells, guided diagnostics calculated network health KPIs that were aggregated for all technologies, by vendor. The KPI formula editor then enabled the user to shape the data to fit their reporting needs, such as the percentage of cells by vendor for LTE, UMTS, and GSM. Trend charts and reports were then aggregated hourly by LTE, UMTS, and GSM technologies, sorted and filtered highlighting the lowest-performing cells including sleeping cells and were then viewed on a GIS map for locating the problem area geographically. Alternate guided workflows could then be used to drill deeper into the causes for the degraded cell performance. The MYCOM OSI out-of-the-box KPI formula definitions and performance reports enabled rapid adoption and incorporation into the operator s work practices. The user-friendly formula editor, which accommodates multiple vendors and release versions, made it easy to update KPIs without modifying reports. Results By providing near real-time visibility and analysis of performance, fault, and configuration data, the operator s LTE networks were launched and operated at peak efficiency, delivering maximum capacity, and with an excellent quality of service. From a staffing perspective, the NIMS-PrOptima automated root cause analysis and workflows increased productivity and enforced consistency.

11 USE CASE Seamless monitoring during network upgrades and swaps CUSTOMER SITUATION A leading European telecom operator that offers fixed line and mobile telephony, broadband, cable TV, internet and coastal radio services to its 3.5 million mobile subscribers required a system to monitor and optimize performance of new radio access and core networks during infrastructure swap-out of old network equipment vendor with new vendor equipment. A Performance Management system was needed to ensure no loss of network and service performance and to enable a smooth transition during the swap. A key requirement was that the system be made up and running quickly with ease of adding new KPIs and reports on the fly. There was a need for future-proof performance management so that the operators LTE RAN and EPC networks could be supported as well. SOLUTION MYCOM OSI offered ready-to-use, off-the-shelf adaptors to collect performance data from network infrastructure (old vendor and new vendor) for quick viewing for both old and new vendor systems. The project was kick-started with the MYCOM OSI PrOptima KPI library to save precious project time. The offered solutions included GIS interface, workspace, alarm module, profiling module and web GUI for enhanced visualization across the network. It provided the capability of benchmarking RAN replacement as the operator moved from one vendor to another. MYCOM OSI created dynamic reports and KPIs as the transition took place. PAC - Report BENEFITS Smooth vendor swap with no subscriber impact Clear vendor acceptance criteria measured on performance benchmarks Improved operational efficiency Improved capacity planning Uniform performance management reporting Improved troubleshooting and reduced trouble tickets QUICK FACTS Customer: European mobile operator with 3.5 million subscribers MYCOM OSI solutions: PrOptima Domains: RAN, circuit-switched core, packet-switched core, evolved packet core Technologies: GSM, UMTS, LTE Vendor equipment: Ericsson, Cisco, Huawei

12 PrOptima was integrated with the operator s inventory system, which resulted in new visibility of the network assets, combined with performance intelligence. PrOptima produced the necessary KPIs/Metrics to indicate whether the new sites (of the new vendor) were good enough to be accepted, as the roll-out happened. This resulted in zero impact to the operator s subscribers during the transition, as all potential problems were proactively highlighted. Some detailed actions performed included: External database integration - Migrating cell/area/cluster information to PrOptima Inventory data migration Generating KPIs for Acceptance Reporting (FAC/PAC) Creating KPIs combining legacy data and new vendor data After the success of the transition, PrOptima was extended to manage the performance of the new LTE EPC based on new network elements, followed by the LTE RAN of the new vendor. Consequently, the system was upgraded to support new circuit core and EPC networks. MYCOM OSI extended the PM system to a new vendor of 2G, 3G and LTE radio networks. RESULTS PrOptima provided the capability of benchmarking RAN and Core replacement as the operator moved from one vendor to another resulting in a smooth transition, with no impact on subscribers. When MYCOM OSI managed the performance of complete E2E 2G, 3G and LTE across core and radio domains, operational efficiency improved manifold. Capacity and troubleshooting reports were made available from the first day. The use of custom KPIs to focus on the most important issues and custom reports to support operational work processes reduced the time to identify problems and troubleshoot them. This also resulted in improved capacity planning and time to resolve for trouble tickets. PrOptima was able to bring uniformity in performance reporting as the operator and vendor used the same PM solution. After the initial swap-over, the operator used PrOptima extensively for the entire E2E performance management, as a trusted management system. The operator was able to use performance criteria for vendor equipment acceptance and payments.

13 USE CASE Taking a unified view to manage performance across multiple domains Customer Situation This European mobile operator had several national operating companies across the world that had deployed IP-based converged networks that simultaneously carried data, voice, and video services originating from mobile and fixed sources. Each company was using siloed systems to manage the performance of their networks, such as 2G, 3G, packet-switch and transport. The systems only managed a specific network domain or technology and required numerous manual tasks. Instead of this narrow approach, the operator wanted to deploy a single performance management solution that would take a unified, end-to-end view across multiple domains and technologies by consolidating performance management data from fixed, mobile, and transport domains. The business goal was to increase operational efficiency, provide more powerful and cost effective performance management, and increase troubleshooting speed and mean-time-to-repair compared to its siloed legacy systems. The operator wanted a consolidated view at the group level as well as for each local company. The solution needed to provide visibility to all network resources and mediate and analyse correlations and performance-impacting relationships between domains, such as RAN and IP backhaul. They wanted to monitor the networks end-to-end, to drill down into network element data, and to perform root cause analysis across varying network domains all from the same platform. The operator chose the MYCOM OSI NIMS-PrOptima carrier grade, converged multi-vendor, multi-technology and multi-domain performance management solution to manage its converged networks. The solution provides out-of-thebox advanced correlation, analysis, reporting, and visualization capabilities that process very large volumes of performance management data. The solution was selected for its ability to provide flexible automation, workflow, alarming, and configuration capabilities and to provide insightful results to multiple organizations within the Group as well as the local operating companies. Solution NIMS-PrOptima provided the operator with powerful end-to-end, unified network performance visibility and insights across domains and across their local companies. Large volumes of data were not only collected and aggregated from a variety of domains, technologies, and vendor devices, but also harmonized in a unified database and then enriched with performance and customer experience data from other sources. Single and composite Key Performance Indicators (KPIs), reports, and dashboards integrated data from all domains. Statistical data were correlated and grouped logically, e.g., by technology, hierarchical network area, region, or service. Topology-driven correlations and cross-domain KPIs provided deep-dive root cause analysis into individual network elements. BENEFITS Near real-time monitoring, alarming, reporting, and network diagnostics Billions of data points processed per hour Automated data analysis to detect complex performance degradations Automated workflows and issue resolution processes Multi-vendor, multi-technology, multi-domain Unified, end-to-end fault, configuration, performance, and trouble ticket processing Powerful, integrated GIS capabilities Flexible, out-of-the-box KPIs and reports aligned to workflow processes QUICK FACTS Customer: European mobile operator, 15 million subscriber base MYCOM OSI solutions: NIMS-PrOptima Domains: RAN, IP backhaul Technologies: Radio access network (2G, 2.5G, 3G, 4G), Packet and circuit core networks, transmission, VAS platforms Vendor equipment: NSN, Ericsson, Cisco, Huawei

14 To resolve performance issues the user could, for example, map RAN network elements to backhaul or core network elements, drill down to RAN elements, and then across backhaul to core elements. Trending, diagnostics, and alarms enabled them to proactively prevent network performance issues. Even more efficiency was gained by using NIMS-PrOptima Decision Support System that automatically performed calculations and evaluations through terabytes of network performance data tasks that were previously performed manually. The operator used this flexible and extensive process automation capability to automate root cause analysis across domains and often configured it to suggest or take action for resolution. NIMS-PrOptima was also used to automate repetitive performance and network engineering processes and capture best practices to increase efficiency and effectiveness. Visual correlations across domains, technologies, and vendors, as well as across the company, were viewed in a single dashboard. Data points from any network domain could be consolidated into a single performance view. A drag-and-drop user interface made it easy to take a multi-domain view, roll up and drill down between domains and assess traffic across multiple network domains. This provided the operator with insights that were not previously attainable and significantly reduced the time required to identify problems. NIMS-PrOptima consolidated performance data from different domains into single reports that could show, for example, daily aggregated RAN domain health statistics by technology or daily aggregated epc domain, IMS Network, DWDM, or VAS health statistics. By selecting any data point the user initiated drill-down and diagnostic workflows. Quality and network statistic reports were able to be distributed to operations, marketing, and business organizations in real-time. Results NIMS-PrOptima provided a consolidated end-to-end performance view across all network domain assets, including 2G, 3G, 4G, core, router, and microwave technologies. All data from radio, transport, and IP devices were mediated by NIMS-PrOptima. By providing visibility and analysis of performance across domains the operator quickly visualized, troubleshooted and managed network performance degradation across traditionally isolated domains. For example, they could point to an IP Interface experiencing instability and then navigate and correlate to related network domains. The multi-domain robust and flexible reporting capability enabled continuous end-to-end performance visibility at both Group and local levels. Readily available KPIs and automated analysis enabled the operator to quickly develop and customize the reports it needed. Intelligent, automated workflows increased productivity and enforced consistency. The result was increased operational efficiency and, by quickly resolving service impacting network issues, customer satisfaction.

15 USE CASE Realizing the vision of unified performance management CUSTOMER SITUATION A very large Asian mobile and fixed operator was building a Super Network Operations Centre (SNOC) for efficient management of its entire national network, to speed up the integration of new equipment and technologies, as well as to convert network data into information to the benefit of its large subscriber base (185 million subscribers). The SNOC, which was based on services-driven network management, required a Performance Management at its core to carry out the critical functions required. Committed to delivering the best network quality and customer experience, the operator was rolling out an aggressive voice and data growth plan. The massive size of the network deployment and subscriber base required a single, carrier-grade network performance system to meet the scalability requirements of the multi-vendor, multi-domain network. BENEFITS Customer impact and loss analysis Proactive notification from network to business and/or customers Predictive network problem detection Optimization of revenue Dashboard view of the network and services for the C-level as well as operations teams Increased operational efficiency and higher productivity Improved customer experience through reduced MTTR, end-to-end SLA for services and proactive service impact QUICK FACTS Customer: Asian mobile and fixed operator with 185 million subscribers and 700K cells Performance management scalable architecture However, there were challenges in implementing a large scale performance management solution using legacy tools. The umbrella performance management was required to have service quality impact analysis, support for multi-technology, multi-vendor, across multi-domains to handle SNOC service level complexity. The solution was expected to be highly scalable, offering a robust solution to consolidate the different performance data sources.

17 USE CASE Monitoring and analyzing issues across RAN and IP backhaul networks Customer Situation Lacking an integrated performance management solution, this European mobile operator had one group of specialists who focused on managing the Radio Access Network (RAN) using a dedicated set of tools, and another team with different set of dedicated tools who monitored and analyzed its IP backhaul network. This siloed situation depended on manual processes, if any were used at all, to analyze correlations and performance-impacting interrelationships between the two domains. The operator wanted to increase its operational efficiency, troubleshooting speed, and mean-time-to-repair by managing both RAN and backhaul domains from the same network performance management solution. They wanted to monitor the network end-to-end, allowing drill down to problem elements across technologies, and to perform root cause analysis across both network domains all from the same platform. Composite Key Performance Indicators (KPIs), reports, and dashboards were needed to encompass data from both RAN and backhaul domains. The operator chose the MYCOM OSI NIMS-PrOptima performance management solution because of its ability to manage multiple technologies and equipment vendors across access, backhaul, core and service domains. It was also important to have out-of-the-box advanced correlation, analysis, reporting, and visualization capabilities from one single graphical user interface. The ability to process very large volumes of performance management data in near real-time was also required. Solution NIMS-PrOptima opened up a new world of capabilities to the operator. Instead of narrow, siloed perspectives, they could now gain powerful insights and end-to-end network performance visibility across both RAN and IP backhaul domains that improved operational efficiency and led to faster mean-time-to-repair. Data were not only gathered in near real-time from both RAN elements and backhaul transmission devices, but the data were loaded and harmonized in a unified database. This enabled visual correlation of cross-domain data in a single dashboard, as well as reports that combined data from both domains, multiple technologies, and multiple vendor equipment. Single, composite, cross-domain serviceability KPIs that contained sub-kpis from the different domains were created. Statistical data were aggregated from each domain and correlated or grouped logically by technology, region, or service. The user had the capability to drill down from the crossdomain serviceability KPIs into individual domain component elements. The operator took advantage of the solution s ability to perform topology-driven correlations, i.e., to correlate KPIs, drill down, and roll up for deep-dive root cause analysis. BENEFITS Multi-domain, multi-vendor, multi-technology Flexible, out-of-the-box, multi-vendor KPIs and geographical and cluster-based reports Advanced and historical correlation, analysis, reporting, and visualization capabilities Powerful, integrated GIS capabilities Automated analysis to detect performance degradations Improved operational efficiency QUICK FACTS Customer: European mobile operator, 15 million subscribers (Group Level) across 3 countries MYCOM OSI solutions: NIMS-PrOptima Domains: RAN, IP backhaul, IP/UPM Technologies: GSM, UMTS, LTE Vendor equipment: Huawei, NSN, Juniper, Cisco, Ceragon, Flexihybrid

18 To resolve performance issues the mapped RAN network elements to backhaul and/or core network elements used in the initial analysis could be used as a starting point for drill down to isolate the domain and specific network elements where the serviceability was being effected. In addition, the users created quality-indexed, multi-domain KPIs to rank the worst sites based on both radio and backhaul performance. Even more efficiency was gained by using the NIMS-PrOptima Decision Support System (DSS) that automatically performs calculations and evaluations through terabytes of network performance data. This was previously performed manually. The flexible and extensive process automation module allows the users to embed multiple decision trees for simultaneous and automatic root cause analysis across RAN and backhaul domains with recommended actions for resolving issues on identified problem elements. One example of a cross-domain operational troubleshooting workflow starts by identifying a NodeB with a high call drop rate. Traversing to the Cell Site Gateway, the user can see if the call drop rate is isolated to the UMTS network or if the GSM and LTE cells which share a common Cell Site Gateway are also affected. Then further traversing using the rollup or drill down functionality to the backhaul network, the user can check key resource KPIs along the way. Thus, the user quickly determined whether the problem was latency degradation, or a pseudo-wire availability, or traffic utilization problem in the backhaul network or was caused by QoS dropped packets at a Mobile Aggregation Site Gateway. The user could see synchronized views of RAN and cell site router data within the same workspace and then manage and monitor the links between the cell site gateways and the aggregation routers. The ability to see a multi-domain view, roll up and drill down between domains, and assess traffic across both IP and mobile networks provided the operator insights that were not previously attainable in standalone single domain solutions. This significantly reduced the time required to identify problems. Results NIMS-PrOptima provided critical cross-domain monitoring and analysis of RAN and IP backhaul networks. By providing near real-time visibility and analysis of performance across domains it was possible to quickly visualize, troubleshoot, and manage network performance degradation across traditionally isolated domains. This resulted in improved operational efficiency, rapid troubleshooting time, and reduced mean-time-to-repair all of which resulted in excellent quality of service. The NIMS-PrOptima powerful GIS capabilities, the robust and flexible reporting, the readily available KPIs and automated analysis enabled the operator to quickly develop and customize the reports needed. In addition, intelligent, automated workflows increased productivity and enforced consistency. The scalable converged performance management solution is highly flexible and processes very large volumes of performance management data in near real-time. The NIMS-PrOptima system is capable to support complex use cases that depend on the ability to show relationships between different network elements from different domains.

19 USE CASE Transforming performance management to increase customer satisfaction Customer Situation This very large Asian operator s goal was to differentiate itself based on network quality. They wanted to use end-to-end network performance insights to deliver a superior customer experience. But end-to-end performance management was not feasible even at a small scale with their multitude of technology-, domain-, and region-specific tools and manual processes. Instead, they transformed and consolidated their operations by creating a centralized Super Network Operations Centre that would manage one of the largest networks in the world. To do this, the operator required a performance management solution that would take a unified, end-to-end view by consolidating and harmonizing data from their entire network, including multiple domains, vendors, releases and technologies across 23 operating areas with 150 million subscribers. The robust solution needed to support their massive network scale provide near real-time data availability, analysis and reporting, automate routine tasks, unify processes and support proactive management. It also needed the flexibility to support current and future complex services and technologies. The operator chose the MYCOM OSI NIMS-PrOptima carrier-grade multivendor, multi-technology and multi-domain performance management solution to harmonize and analyze very large volumes of network data in near real-time, speed the integration of new equipment and technologies and use network insights in ways that benefit subscribers. A critical feature was NIMS-PrOptima ability to dynamically link access, transmission, core, and VAS domains into service models aggregating across domains, vendors, or technologies. Out-of-the-box advanced correlation, analysis, drill-down, reporting, and visualization functions enable proactive management. At the same time flexible automation, workflow, alarming, and configuration capabilities reduce mean-time-to-repair and improve operational efficiency. Solution NIMS-PrOptima provided the operator with powerful end-to-end, unified network performance visibility and insights across its regions. Large volumes of data were not only collected and aggregated in near real-time from a variety of domains, technologies, and vendor devices, but also harmonized in a unified database and then enriched with performance and customer data from other sources such as billing systems. Individual and composite Key Performance Indicators (KPIs) were correlated and grouped logically, e.g., by technology, hierarchical network area, region, or service. Cross-domain KPIs and topology-driven correlations sped root cause analysis and were even used to determine the impact of specific user devices on the network. Trending, diagnostics, alarms, and easy deep-dives into individual network elements enabled the operator to proactively prevent network performance issues. BENEFITS Unified performance management across domains, vendors, releases, technologies Large library of out-of-the-box, up-to-date interface adaptors Carrier-grade robustness and massive scalability Performance visibility across all domains Near real-time collection, mediation, and aggregation of any network data Advanced end-to-end correlation, analysis, reporting and visualisation Flexible, out-of-the-box, multi-vendor KPIs and geographical and clusterbased reports Closed loop automation of processes, diagnostics and analyses Ad hoc analysis across all data via a flexible drag-and-drop graphical user interface QUICK FACTS Customer: Asian mobile operator, 150 million subscriber base MYCOM OSI solutions: NIMS-PrOptima Domains: Radio, transport, IP Technologies: Radio access network (2G, 2.5G, 3G, 4G), packet and circuit core networks, transmission, VAS platforms Vendor equipment: Ericsson, Juniper, Cisco, Huawei

20 NIMS-PrOptima automatically detected changes in network behavior, site expansions, new vendors or new domains and automatically adapted KPIs and reports so that they always represented the true network situation. Even more efficiency was gained by using the NIMS-PrOptima capability to automatically perform calculations through terabytes of network performance data tasks that were previously performed manually. The operator used this flexible and extensive process automation capability to automate root cause analysis across domains and often configured it to automatically suggest resolution or take action. NIMS-PrOptima was also used to automate repetitive processes and capture best practices to increase efficiency and effectiveness. Dashboards showed correlations across domains, technologies, and vendors, as well as across the company, consolidating any data points into a single view. The drag-and-drop user interface made it easy to take a multidomain view, roll up and drill down between domains, and assess performance across multiple networks. This provided the operator with insights that were not previously attainable and significantly reduced the time to identify and resolve problems. NIMS-PrOptima automatically created consolidated reports that could show, for example, daily aggregated RAN health statistics by technology or vendor, nationwide or for specific areas. Results NIMS-PrOptima provided a consolidated end-to-end performance view on a massive scale across all of the operator s network domains. All data from radio, transport, and IP devices were harmonized by NIMS-PrOptima. By providing near real-time visibility and performance analysis across domains the operator quickly visualized, troubleshot, and managed performance degradations across traditionally isolated domains. Flexible dashboards enabled continuous end-to-end performance visibility at both country and regional levels. Outof-the-box KPIs and automated analyses enabled the operator to quickly develop and customize reports. Intelligent, automated workflows increased productivity and enforced consistency. They detected issues and performed root cause analysis and automated healing, tuning, and optimization that boosted productivity up to 50%. Proactive monitoring of KPIs reduced downtime and increased network quality, thereby reducing churn. By consolidating performance management across the country the operator increased its operational efficiency, lowered total cost of ownership, and improved customer satisfaction.

21 USE CASE Reducing alert floods through alarm aggregation Customer Situation A US Communications Service Provider (CSP) managing wireless switches and infrastructure risked mass outages from weather-related storms and natural disasters. Hurricane or tornado seasons greatly impacted the customer with loss of service alerts and the cascade of alert notifications that various devices generated during inclement weather conditions. With a mature rule set and a distributed network, the customer already utilized multiple features of MYCOM OSI NetExpert that drastically reduced the ratio of alarm data processed to alerts generated reducing tens of millions of alarms processed daily, ultimately only generating thousands of alerts. The customer wanted Network Operations Centers (NOC) operators to remain aware of weather-related or natural disaster conditions, yet the challenge was the overwhelming amount of information received during adverse weather events. Devices generating the majority of these alarm notifications could overwhelm and fully occupy the entire fault management system due to their sheer volume of transactions. Stopping the gateway or suppressing transactions to avoid the condition was impractical since other alarm conditions that still required attention could be embedded in the alarm flood. BENEFITS Implemented and tested the new solution in just 2-3 days, with only a minor amount of customization Reduced daily transactions on the Gateway from 200,000 to 20,000 Reduced alarms generated from 30,000 a day to 2,000 Helped NOC operators to manage alert floods and noisy devices Improved overall fault management system performance, including automation STORM CONDITION WITHOUT ALARM AGGREGATION ALARM AGGREGATION REDUCES STORM CONDITION QUICK FACTS Customer: US CSP FLOOD OF ALARMS GATEWAY STORM ALERT FLOOD OF ALARMS GATEWAY GATEWAY ALARM AGGREGATION NetExpert Gateways Storm impact is avoided by Alarm Aggregation reducing actionable events. MYCOM OSI solutions: NetExpert, MYCOM OSI installation and configuration services STORM ALERT The solution required the ability to identify the start and end of an alarm flood condition without the loss of data. The solution also needed to pinpoint the best alarm candidates for aggregation management. Finally, the customer also wanted to avoid manual actions required by operators to identify and invoke any special actions. Therefore, the capability to identify the flood condition needed to be solely based on the rate of alarm transactions received during a defined time interval. Solution Evaluating the customer s systems, operator input, and alert reports, MYCOM OSI targeted three device classes that were generating excessive alarm transactions during nominal and adverse conditions. These were not the only device classes to generate excessive alerts, but they were the noticeable offenders.

22 Using customer input and historical alarm data, the team devised a list of targeted alerts for each Managed Class. These lists identified the individual or groups of alerts that were the most or least problematic generating the largest amount of transactions. This list then became an inclusion list of high volume targeted alerts for that class. For other classes, this list evolved into an exclusion list of the few alarms that were NOT involved leaving all other alarms as candidates. For this customer s rule sets within Gateway Analysis, OSI mapped the Affected Managed Object, Alert Name and Alert Severity into Alarm Aggregation attributes just prior to the location where control passes to the rules engine or policy engine. The team then added aggregation management attributes to the Managed Class, which would store the list of alerts to target for aggregation. (These updates are often the only customizations required for implementing Alarm Aggregation management ). Providing a configurable threshold of transactions during the aggregation interval solved the requirement to indicate the start and end of a flood condition. This Flood Threshold value is used to indicate the count of transactions processed when a flood threshold alert is generated on behalf of the offending alert. An alert, with the naming convention of Flood Threshold (original Alert name) is created when the flood threshold is met or exceeded. If the flood threshold alert exists, it is only updated, which indicates that this alert instance is still experiencing an excessive rate of data. Once the flood condition has subsided, the flood threshold alert is no longer updated and subsequently times out and clears. Using customer input, MYCOM OSI loaded the aggregation management parameters for each Managed Class to identify how the alerts were to be aggregated within the Generic Gateway. The small customization and code insertions were made into the Gateway Analysis rule sets for these Managed Classes. Automating these processes via scripting expedited the transition. Results After one month of production, the customer reported one of the targeted devices reduced the daily gateway transactions from 200,000 to 20,000. The device now only generates approximately 2,000 alerts per day. The device used to generate over 30,000 alerts per day before the changes. We have taken this device from a top 10 noisy Element Management System (EMS) perspective to a fairly quiet device. Each of the automated Managed Classes showed the same improved results. The entire NetExpert system showed better performance and operators using Alert Navigator saw fewer alert transactions and an enhancement in user interface response. ELEMENT CLASS MANAGED CLASS #1 MANAGED CLASS #2 TOTAL Total Alarm Data Transactions Percentage of Processing calls AVOIDED Total transaction SAVINGS by Aggregation 1,589,115 2,301,772 3,890, % 59.48% 70.94% 1,391,020 1,369,014 2,760,034 The effort to determine the busiest or noisiest gateways, especially when identifying offending alerts, resulted in benefits beyond the initial attempt to manage through alert floods. The aggregation management configuration allowed operators to identify target alert instances that were noticeable during storm conditions, and also highlighted noisy alert instances during nominal times, which was an unexpected advantage producing noticeable positive results. Statistically speaking, in approximate terms, Alert Aggregation provides a minimum of a 33 percent reduction in actionable items from a gateway once three instances of an alarm data are received within an aggregation time interval. That reduction jumps to 50 percent when four or more instances of alarm data are received. The Alert Aggregation functionally provided the customer a feature rich way to avoid alarm floods while still indicating the presence and passing of this condition, along with providing detailed data on the condition. The solution was a bolt on into existing legacy rule sets and required only a minor amount of customization; therefore, it did not impact the way alerts are currently processed or managed by that rule set. Since the solution was implemented at the Managed Class level, it could be selectively applied where deemed necessary. In just two to three days, the solution was implemented and tested, and the customers development staff quickly comprehended and utilized the features of Alarm Aggregation.

23 USE CASE Rapid scalability with high-volume alarm processing Customer Situation This long-standing US Communications Service Provider (CSP), managing wireless switches, transport and infrastructure across the United States, utilizes multiple features of MYCOM OSI NetExpert to drastically reduce the ratio of alarm data processed to alerts generated. Expanding into more locations now that this customer was going to be acquiring companies through its growth strategy, the CSP needed to scale its system to manage the increase in devices on the network. SUBORDINATE SYSTEM 1 LOCAL GATEWAYS Solution DB SUBORDINATE SYSTEM 2 LOCAL GATEWAYS P2P NetExpert SUBORDINATE SYSTEM 3 LOCAL GATEWAYS NetExpert SERVICE CENTRAL TOP-LEVEL CONTROL Shown here: MYCOM OSI NetExpert scales to multiple sites while maintaining a single top-level presentation system to display alerts. The P2P application allows for two-way communication. The bulk of the processing occurs in the subordinate systems, which reduces the alerts displayed on the MYCOM OSI NetExpert top-level presentation system. DSS Cluster SUBORDINATE SYSTEM 4 LOCAL GATEWAYS SUBORDINATE SYSTEM N DB DB DB SUBORDINATE DB DB SYSTEM 0 MASTER DB OF COMMON OBJECTS DSS DB LOCAL GATEWAYS The MYCOM OSI team replicated and scaled the NetExpert system by connecting multiple NetExpert systems through the Peer-to-Peer (P2P) application along with a supporting feature set, called Service Central. Allowing for load balancing and distribution of services, Service Central utilizes a single system for presentation and consolidation of alerts and multiple lower level systems that provide the actual alarm processing for all managed devices. Using P2P and Service Central, the MYCOM OSI team ultimately provided two regional Network Operations Centers (NOCs) the ability for centralized network control. The two individual locations are each supported by a geo-redundant Disaster Recovery (DR) setup, which is periodically synchronized with the production system using a Service Central enhancement called Service Central Mirror. These two Service Central configurations have continuously expanded and now support a total of 16 subordinate NetExpert systems that utilize 2000 gateways and support approximately 200 operators. BENEFITS Scalability increased raw alarm data processing power Reduced maintenance activities across multiple instances of NetExpert (via DSS, Database Sharing Service) Retained all existing hardware and software solutions, while allowing integration of newly-acquired acquisitions into the Service Central system QUICK FACTS Customer: US CSP MYCOM OSI solutions: NetExpert, NetExpert Peer-to- Peer (P2P) Gateway Central, Web Alert, Database Sharing Service (DSS), consulting on configuring, integrating, and deploying new NetExpert systems (from company acquisitions) with the existing Service Central configuration

24 With multiple NetExpert systems available for alarm processing, the customer had the opportunity to delineate and segregate its network fault management by focusing individual subordinate NetExpert systems to manage by device class, technology, vendor, service or geography. Although defining management categories was not necessary, it enabled the customer to provide focused services and assisted with the load balancing of the subordinate systems. By introducing Database Sharing Service (DSS) Clustering into the setup for the subordinate systems, these NetExpert systems could share multiple components such as rulesets, managed objects and their relationships. In addition, DSS inherently provided benefits such as a single point of update for all rules and managed objects along with the ability to add a new system quickly by setting up additional shared nodes, which are essentially additional NetExpert instances. DSS also advanced the ability for each NetExpert system in the cluster to provide redundancy and to have the ability to take over for each other since they all shared the same rules and object models. As long as the managed devices were reachable, DSS could provide each system the capability to manage the duties for any other system. RESULTS The implementation of Service Central allowed the customer to continue to utilize all of its existing hardware and software solutions that were created initially, without having to re-engineer or drastically change the way devices were monitored or managed. To simplify load balancing, the customer decided to implement DSS at the subordinate level, which allows each individual system to retain the ability to manage any device class in its network. The chart below shows the amount of raw alarm data messages that are now processed monthly using Service Central and the ultimate number of alerts displayed to the operators using a combination of rules, advanced fault management features and correlations. Both of the newly installed systems regularly manage these volumes and have plenty of room left for additional growth. MONTHLY VOLUME EAST WEST TOTAL Raw Messages 73,700,000 69,300, ,000,000 Alerts Generated 676, ,000 1,443,000 Alerts Displayed 155, , ,000 In addition, the installation of Service Central Mirror allowed the primary servers to periodically or manually synchronize all active alerts into the geo-redundant DR setups. Service Central Mirror therefore allows the DR systems to contain all active alerts that are present in the production system, which provides for minimal impact on operators upon transitioning to the DR systems.

25 USE CASE Prioritizing broadband network alerts in inclement weather conditions CUSTOMER SITUATION A leading European telecom operator that offers mobile telephony, fixed telephony and broadband services to its subscribers required a system to enhance its existing fault management system to handle overwhelming alarm situations during inclement weather conditions, typically thunderstorms. In absence of such a system, the operator risked mass outages as a cascade of alert notifications hit the operator s NOC. Thunderstorms were causing the generation of a flood of alarms from the devices/elements in the operator s broadband network. These were being reported as power supply problems, power cut-offs, etc. from every affected device across the affected areas of the national network. Efficient handling of the alarms was not possible as the operator could not distinguish real alarms from the spurious/transient alarms, or those that were of a lower priority. In addition to this, the flood of alarms slowed down the Fault Management system. Typically, tens of thousands of alarms were raised within 30 minutes during a thunderstorm, whereas the operator did not expect more than a few thousands of alarms on a normal day. The operator required regulated alarm filtering based on policies so that the most relevant alarms were filtered and presented to the users, without losing any critical alarms embedded within the alarm flood. The operator wanted to reduce the alerts by profiling them by severity and class of the network device/ element that raised the alarm. SOLUTION The offered solution included the MYCOM OSI NetExpert DMP (Distributed Management Policies) server with the AFM (Advance Fault Management) module. BENEFITS 30%-50% reduction in actionable alerts Avoid alarm floods while still indicating the presence and data of the flood condition Plug-in DMP module on existing FM system, requiring minimum customization Manage alert floods and noisy devices Improved FM system performance QUICK FACTS Customer: European broadband operator MYCOM OSI solutions: NetExpert DMP-AFM module Domain: Broadband Vendor equipment: Alcatel-Lucent, Huawei, etc. STORM CONDITION WITHOUT ALARM AGGREGATION ALARM AGGREGATION REDUCES STORM CONDITION FLOOD OF ALARMS GATEWAY STORM ALERT FLOOD OF ALARMS GATEWAY GATEWAY ALARM AGGREGATION NetExpert Gateways Storm impact is avoided by Alarm Aggregation reducing actionable events. STORM ALERT

26 The DMP module provided the required advanced policy configuration to prevent event storms (e.g. during thunderstorms). Evaluating the customer network, operator input and the alarm reports, MYCOM OSI targeted specific device/element classes that were generating excessive alarm transactions during the thunderstorms. Using the customer input and historical alarm data, a list of targeted alerts for each Managed Class was devised. These lists identified individual or groups of alerts that were the most or least problematic generating the largest amount of transactions. MYCOM OSI mapped the Affected Managed Object, Alert Name and Alert Severity into DMP-AFM attributes, in order to create the policies within the DMP-AFM module. The beginning and end of the thunderstorm period was also indicated through a flood threshold value, which indicated the count of transactions processed when a flood threshold alert was generated because of an offending alert. If the flood threshold alert existed, this indicated that the alert instance was still experiencing an excessive rate of data. Once the flood condition had subsided, the flood threshold alert was no longer updated and subsequently timed out and cleared. RESULTS Within a month of deployment, the operator reported drastic reduction of alarm alerts from the targeted devices, from hundreds of thousands in a day to a few thousands. Each of the automated Managed Classes showed the same improved results. The entire NetExpert Fault Management system also showed better performance and the users saw fewer alert transactions and an enhanced user interface response. The effort to determine the busiest or noisiest devices, especially when identifying offending alerts, resulted in benefits beyond the initial attempt to manage alert floods. The DMP-AFM policy configuration allowed the operator to identify target alert instances that were noticeable during thunderstorms, and also highlighted noisy alert instances during nominal times.

27 USE CASE Dynamic inventory access Customer Situation A Communications Service Provider (CSP) required a provisioning system to provide new services to its customers. The CSP wanted to ensure that its customers received optimal service the moment the service contract began, so that they would continue to renew their contract with the CSP. Most importantly, the CSP wanted to be able to ensure that network resources were available and not in a fault state before provisioning took place. Solution MYCOM OSI worked with the CSP to provide a MYCOM OSI NetExpert based framework with eight NetExpert systems managing four different regions. The CSP wrote all of the provisioning and business rules in the NetExpert 4G (4th Generation) rule language, and the NetExpert database contained all the necessary inventory information. BENEFITS Ensured optimal services from the moment the service contract began Provided assurance that the DSL circuit had been provisioned correctly and was operating at optimum bandwidth Helped increase customer satisfaction, achieving 99.6% provisioning success rate QUICK FACTS Customer: CSP, 3.6M subscribers MYCOM OSI solutions: NetExpert, Generic Gateways Third-party products used: Tollgrade Test Systems Driven by the powerful NetExpert platform, the MYCOM OSI Generic Gateways communicated with a third-party test system tool (Tollgrade), performing loop testing to find the optimal bandwidth and assuring that the required network resources were available to provision. Based on data derived from this testing, NetExpert fine-tuned the customer bandwidth, ensuring optimal service and customer experience.

28 RESULTS With over 60,000 managed devices, 3.6 million subscribers, 550 operators (users), and 20,000 provisions per day, the CSP achieved reliable, automated flow-through provisioning utilizing the MYCOM OSI Generic Gateways and rules to drive test applications.

29 USE CASE System consolidation and integration of non-standard SNMP interfaces Customer Situation A Communications Service Provider (CSP) in Europe purchased equipment that did not conform to integration standards, creating a diverse network management environment. The customer needed to manage unsolicited messages (traps) from the Simple Network Management Protocol (SNMP) gateway agents in its managed network. Since the SNMP interface did not follow the standard integration model of supplying a Management Information Base (MIB), trap processing became a challenging task. It was difficult for the customer to comprehend the information coming in, slowing down and complicating the overall process of integration. BENEFITS Reduced administration time by providing templates for complicated tasks Overcame a non-standard SNMP device integration model Reduced overall cost of ownership by consolidating management systems Shown here: Using DMP templates to extract data, the customer integrated non-standard network devices using MYCOM OSI NetExpert as a Manager of Managers. NetExpert enabled the customer to deal with an inconsistent SNMP interface as well as consolidate management systems reducing cost of ownership. REDUCING COST OF OWNERSHIP THROUGH CONSOLIDATION QUICK FACTS Customer: European CSP IP DEVICES W/O MIB Traps Traps GETs ICMP Ping GATEWAY AGENT IP DEVICES W/ MIB IP DEVICE GATEWAY AGENT TIMER IP DEVICE GATEWAY AGENT TIMER MYCOM OSI solutions: NetExpert, Distributed Management Policies (DMP), SNMP Gateway Agent, development services to manage SNMP devices NetExpert DMP Policy Engine Solution The MYCOM OSI team used the MYCOM OSI NetExpert Distributed Management Policy (DMP) templates to achieve trap management for monitoring. The templates included pre-defined actions to speed up the process of managing the network. To allow the fault management system to manage traps, the team configured a Gateway Agent to receive SNMP traps on a specific host and port address. When DMP received the trap data from the SNMP Gateway Agent for processing, DMP performed additional data processing including building the Affected Managed Object (AMO) Name, Alarm Name and similar information. If the Managed Object (MO) did not exist in the fault management system, DMP created the MO and then generated an alert based on the incoming trap data. When the alarm cleared, the incoming trap s state changed to OK in lieu of PROBLEM, and the accompanying alert in the fault management system was set to NORMAL, indicating the alarm condition was no longer present.

30 RESULTS Using NetExpert as a Manager of Managers, the customer reduced total cost of ownership by reducing its licensing fees through consolidating management systems into NetExpert. In addition, NetExpert enabled the customer to be able to deal with an inconsistent SNMP interface that was not following the standard integration model of supplying a MIB. Since the traps coming in from an SNMP device are received in a fixed format, the MYCOM OSI team found patterns in the data, so that the relevant data could be processed for further usage. Using DMP templates, the team extracted basic alert information and values for extended alert properties, which consisted of tailored customer data. The MYCOM OSI team developed and leveraged pre-defined templates that offered pre-defined actions. This DMP template was designed to receive traps in an XML format from the gateway agent. The template understands the pattern of the information coming in, and intelligently deciphers and extracts the relevant information. For example, to format the IP address received from the SNMP trap to form the AMO for the alarm to be generated, the IP address was reformatted with underscored lines replacing dots and created under class IP. The figure below shows the type of incoming data that was extracted and concatenated to form new fields in the template (dummy data has been italicized to protect confidential data). The pre-defined template offered ease of use, enabling NetExpert to integrate with different vendors and data formats.

31 USE CASE Improving trouble ticket accuracy and processing through automation Customer Situation A European Communications Service Provider (CSP) needed to improve the time required to obtain information on impacted customer services. Adhering to this constraint would ensure the Service Management Center (SMC) technicians could assess impacts and respond to customer issues quickly improving the customer experience. In addition, the SMC, also known as the Network Operations Center (NOC), needed to dispatch tasks to technical resolution teams with all necessary information, including the root cause, the Ticket ID and the expected Time of Resolution, to ensure lean and accurate communication to both customers and management. Solution Because the integrated Trouble Ticket creation capability was offered as an add-on to the MYCOM OSI NetExpert Service Impact, the MYCOM OSI team chose NetExpert Trouble Ticket Adapter (TT-AR) to integrate with the TT system (Remedy). Within the TT system all communication details about customers, products, services and elements were pre-loaded. This allowed for segmenting precise and proactive communication to customers, internal management and dedicated customer facing teams. Providing correct and timely information to specific audiences, such as top revenue-producing customers, reduced churn. NetExpert Service Impact leveraged NetExpert dialogs feature to automatically receive and send actions for processing in the TT system. This allowed the customer s SMC to manage and dispatch tickets through NetExpert Service Impact quickly, such as associating and disassociating ticket automation capabilities with events. BENEFITS Focused on correct priorities with fast-track issue handling Reduced manual data entry time from ~30 minutes to ~2 minutes per incident Improved ticket data accuracy Improved uniform communication to corporate groups Improved processing by automating dispatched ticket updates as they were received QUICK FACTS Customer: European CSP MYCOM OSI solutions: NetExpert Service Impact, NetExpert Trouble Ticket Adapter (TT-AR), installation services Third-party products used: Oracle v11, Remedy 7.5, Sun M core, 2.52 GHz Ultra-SPARC T2 hardware, Sun T core 1.2 GHz Ultra-SPARC T2 hardware For example, the SMC technicians could create a ticket using the NetExpert TT-AR interface to send all affected customers information about impacted products, services and elements. Any new impacts were automatically added to existing trouble tickets.

32 RESULTS With 7 million objects and corporate customers or customer groups managed, not only did the SMC improve mean time to repair/resolve (MTTR), but an unexpected secondary benefit resulted from the CSP s account managers and legal staff using the solution. Both parties were able to access the tool for timely information. And, in addition, customer advocates, who look at outages on a customer site to take action and resolve outages, were able to use the information to solve their issues. Just as important, data accuracy improved while the SMC saw a reduction in manual entries by operators for re-keying errors since consistent data was now shared between systems. It can be estimated that a configuration of this size may generate an average of potential manual data entry requirements per hour, demanding 2-3 minutes each of staff time, if handled by a skilled operator. The NetExpert automation capabilities reduced that consolidated administration time from around one hour to approximately one minute. In addition, NetExpert eliminated the risk of manual data entry errors during ticket creation and ticket updating, which avoided miscommunication.
